Chess Openings Encyclopedia 2011: 500 000 Expert Evaluations

Openings Encyclopedia 2011 is an excellent tool for studying the openings, building opening repertoire and fast games database searching.

This excellent program for learning chess openings includes theoretical material on every opening, a user-friendly and detailed classification of variations, a quick search option and an option for analysing games and positions.

There are two ways of studying an opening: by looking through encyclopedic tables for chosen openings or variations and by moving along a Chess Tree displaying expert evaluations of a current position.

Openings material is based upon:• 500 000 of expert evaluations, which were verified and corrected by Rybka • 8 000 annotations to key moves• 40 million of evaluations by Rybka engine• Database of 4,350,000 games as of April 1, 2011.

A Rybka 2.3 program is integrated into the Encyclopedia with a possibility of simple connection to Rybka 4 or other UCI and Winboard engines. A powerful system of search according to player’ name, position, positional element, motif and material correlation is supported.

A test of opening mode will allow you to test your knowledge and your skill of playing in your chosen opening against the program and to obtain recommendations automatically.
